3.2 SS taking shape
Hi guys, finally got organized enough to start my engine build. Standard 3.0 crankshaft was machined at Ollies- it looks too good to hide inside the case! Tightening the rod bolts was the SCARIEST thing i have ever done. I put together a tool to mount my dial guage and got the stretch measured @ 0.006 inches. The complete crank is now sitting on my desk- taunting me to find the time to continue the build...

Carillo rods, eh? Why'd you go Carillo over another brand? I have heard the different pitches, but am always curious about decisions when dollars change hands. I was going to go Pauter, but the Carillos are lighter.
That crank looks freaking amazing! What was the $ damage if you don't mind me asking? As you can tell, I am just a few steps behind you on a similar course. Can we get pics of the tool you used to do the rod bolt torquing/stretch measurement?

3.2 SS
Hi Kenik,
I didn't exactly choose the rods- i bought someones race car project which included a new set of Carrillos. They are beautifully made and as you say very light. Machining on the crank came to a little over $700- if i was going to build another engine i don't think i would afford this expense. However the crank is now as light as a 2.7... The tool is made up of some parts we had in the lab which will support a dial guage. I'll take a pic soon Brett

Seven hundy, eh? I assume that included a zero balance factored into the fantastic knife-edging they did? Did they do anything else?
Might I say that the crank work you did will pay huge dividends. I seem recall an unfinished 3.2SS project for sale on Pelican awhile back. Is this the one?

Your comments remind me of when I bought some JE's a few years ago and my wife said, "You're going to hide them in your engine?"

Dave,
I felt the same way! They're way too nice to hide inside the engine and coat in oil... ![]()

For those not in the know, the crankshaft in these pictures has been "knife-edged", which is used to reduce air friction inside the case as the crank turns. Not really necessary for street engines, but good for race engines, when you're trying to extract every last ounce of horsepower...

Hello, all.
The crank also looks to have had an extra oiling hole drilled in it, and a groove round the main journal to increase rod oil flow ate very high rpm. This requires special main bearings, and probably bigger oilways in the block.. Kind regards david |
